Osclosed, the momentary backward spring of the cillating movement of the pawl -4 is adapted to bolt 23 as it snaps into the catch on the frame does not interfere with the position of the window. The pawl l4 merely springs downwards and then upwards again into engagement with the wheel 9, the window meanwhile being under the constant upward thrust of the spring 5.

If, in any instance, the window I is turned downwards by the handle I while standing open, it can be closed automatically by simply turning the door handle (not shown) and thereby freeing the wheel 9 from the restraint of the pawl I l for a sufiicient time.

Various modifications may be made in the means described without departing from the scope of the invention. For example, the pawl I4 or similar release device may be operable upon closing, instead of opening, of the door 20, as, e. g., by actuating it by a wedge-member controlled by a depressible plunger adapted to contact with a stop on the door frame.

In any case, the power utilized to raise the window may be compressed air or other pressure fluid, or electricity. For example, the door handle may simultaneously control a valve or switch putting the power means into or out of operation.

I claim:

1. In combination with an automobile body having a door provided with a window therein and a free edge through which movably projects the usual latch bolt arranged to engage a socket in an adjacent fixed portion of said body, a member engaging the window in said door, mechanism for actuating said member to permit opening of said window, and means controlled by an element actuated by said latch bolt upon retraction thereof automatically operative to actuate the member and close said window independently of said window opening mechanism.

2. In combination with an automobile body having a door provided with a window therein and a free edge through which movably projects the usual latch bolt arranged to engage a socket in an adjacent fixed portion of said body, a member engaging the window in said door, mechanism for actuating said member to permit opening of' said window, means automatically operable to actuate the member and close said window independently of the window opening mechanism, and a control element actuated by said latch bolt upon retraction thereof for causing operation of the last mentioned means to close the window.

3. In combination with an automobile body having a door provided with a window therein and a free edge through which movably projects the usual latch bolt arranged to engage a socket in the adjacent portion of said body, a lever engaging said window, a torque spring tending to actuate said lever in one direction to close the Window, a crank operated. mechanism including a gear for actuating the lever in the opposite direction against said torque spring to permit said window to open, a pawl normally engaging the teeth of said gear for retaining said crank operated mechanism in the position to which actuated in opening the window, and a member actuated by the latch bolt upon retraction thereof operable to disengage said pawl from the gear and permit the torque spring to actuate said lever and close said window independently of the crank operated mechanism.

4. In combination with an automobile body having a door provided with a window therein and a free edge through which movably projects the usual latch bolt arranged to engage a socket in the adjacent portion of said body, a pivoted lever engaging said window, a torque spring tending to actuate said lever in one direction to close the window, a rotatable gear, a link secured to said gear for rotation therewith and having a slidable connection with the lever, a crank device for rotating said gear and link to actuate said lever in the opposite direction against said torque spring to permit said window to open, a pawl normally engaging the teeth of said gear for retaining the same and said crank device in the position to which actuated in opening the window,

and a member actuated by the latch bolt upon l retraction thereof operable to disengage said pawl from the gear and permit the torque spring to actuate said lever and close said window independently of the crank device and the gear and link actuated thereby.
